apache服务器为某些页面提供大写UTF-8，另一些页面提供小写utf-8 charset标头

Question

I am using MAMP to host php pages over and apache server . In my root directory I have a .htaccess file to do some rewrites and other things including adding charsets to the headers of certain files like so:

AddCharset UTF-8 .css .js

Now this code is working fine but I have an issue that is really annoying.

The page test.php returns a bunch of html which contains links to some .css and .js files. Now when I call up the test.php file over my browser it returns the following in the response header for each file:

text/html; charset=UTF-8
text/css; charset=utf-8
application/javascript; charset=utf-8

I really don't understand why it return the charset in upper case for html but in lower case for all other content types. This is not a severe problem of functionality but it really bothers me. To solve this I tried to include the ending .html in the AddCharset like so:

AddCharset UTF-8 .css .js .html

But this does not change anything, it still returns the the charset for the text/html file in user case. Could anyone tell me how to make the server return either consistently upper or lower case charset headers.

Answer 1

After some trying around to see where the charset header was actually set, I discovered that PHP outputs a charset automatically so to change the UTF-8 to utf-8 you need to change the Charset in the php.ini file. This fixed the problem.
